I didn't mean a psychiatric definition, but a common usage, 'dictionary', definition. The point is that you need different words to be able to distinguish between people incapable of displaying social behavior and people that choose to display antisocial behavior part of the time. An asshole boss usually still behaves in a civil way towards his peers and would even show altruism towards them. You can be a complete jerk that proposes that homeless people are lazy bums that should be incinerated and that still doesn't make you a sociopath or a psychopath, if you take out the trash for your disabled neighbour at the same time. To use those words for such people muddles the issue: it suggests a lack of ability where we are dealing with a conviction that can be changed given the right circumstances.

You can't have 1 in 25 people being a sociopath. You can have 1 in 25 people being an antisocial asshole.
